Change the valve? From what I hear, and from limited practical experience, it is highly unlikely you'd get them to fit. Now, if you were REALLY handy, AND the diameter of the existing stem was big enough, you MIGHT be able to machine the stem to fit, but, you'd probably spend more than it would cost to replace the valve and get the handles you want.

That is like putting a Chevrolet part on a Ford. They are not interchangable, and Price Pfister has handles that will match most Delta trim. In the process you should upgrade the PP unit to the new technology.

Plumbers get this question so often that sometimes I would just like to reach out and choke someone! So if some of the replies you receive to this question are a little testy, please be patient with us.

Faucets are not "universal" any more that cars are. You dont go to the Ford dealer to get parts for your CHevvy. You don't call the Maytag man to fix your GE refrigerator.

So, you need to select some Price Pfister handles which suit your style.

thanks for the input. modification of the PP stems took approximately 8 minutes on a bench grinder. as the homeowner, I now have the look I wanted without the hassle or expense of installing a new valve body. this was fortunately a very straightforward "customization."

now if I can just get some ideas for installing Corvette quarter panels on my Ford Pinto . . .

Maybe they need about 20 minutes on the bench grinder. You asked for our ideas and received them and then did your own thing. If you ever sell the house and the faucets have to be repaired, the next owner is going to be less than thrilled to find out that they do not have Delta stems and there are no stems made like that, and that they are going to have to use a bench grinder for about 8 minutes to make new ones. I would be interested in seeing what was so special about those Delta handles, and how you got the to work with the PP escutcheons/flanges, and I assume you still have the old PP compression type stems.
